Pure Black Text/Graphics

The Pure Black Text/Graphics option affects the printout for black
text and vector graphics on a page. Under most circumstances,
leave this option set to On. When Pure Black Text/Graphics is on,
black colors generated by applications (for example, RGB = 0, 0,
0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using
the maximum amount of black toner allowed by the calibration
curve. This means the black text and line art will not exhibit
halftone artifacts (as long as the printer is calibrated correctly)
and will not be misregistered, since there is only one toner used.
In addition, this setting eliminates blasting.
For some jobs, it is preferable to clear this option, for example, if
the page includes gradient fills that use black. The following table
describes the behavior of the Pure Black Text/Graphics option with
black data defined in different color spaces.
